Abstract

The object of the invention is a motor vehicle door lock with an outer housing (11) with an entry slot (12) for a lock hinge (50), with a rotary bolt (13) moving in entry slot (12) and located in housing (11), with a lock pawl (14) holding rotary bolt (13) in locked position and placed in housing (11) and preferably with an electric drive (15) placed in housing (11) for lock pawl (14). This is first characterized in that housing (11) is completely closed externally except for entry slot (12) for the lock hinges and optionally entry fittings (23) for one or two Bowden cables (24; 25) and/or an entry fitting (26) for a lock cylinder. Further, it can also and independently be achieved that another drive motor be placed in housing (11) for motorized movement of rotary bolt (13) and that it be engaged with rotary bolt (13) even when the latter is in the locked position, and rotary bolt (13) is turned increasingly further in the locking direction as the motor vehicle speed increases. Especially significant is also a variant of the motor vehicle door lock in which housing (11) is made essentially symmetrical to its central plane lying in or parallel to the plane of rotary bolt (13) and lock pawl (14) and is provided with an entry slot (12) on both large faces parallel to the central plane.

Claims

1. Motor vehicle lock comprising an outer housing having a pair of opposed large faces, each of which is provided with an entry slot for a lock hinge, a rotary bolt located in said housing and movable within the entry slots, a lock pawl located within said housing for holding the rotary bolt in a locked position, an electric drive located in said housing for moving said lock pawl, and an electrical connection device for electrically connecting said drive to a source of electrical power;

wherein said housing is essentially symmetrical relative to a center plane thereof that lies parallel to a plane of rotation of the rotary bolt with the entry slots being elongated in essentially identical directions that are parallel to said center plane on opposite sides thereof; and

wherein said electric drive is positioned between said entry slots, the symmetry of the housing and the positioning of the entry slots and electric drive enabling mounting of the housing, selectively, at either of said opposed large faces for use at both left and right sides of a vehicle.

2. Motor vehicle lock according to claim 1, wherein an entry fitting for at least one Bowden cable is provided on a narrow side of the housing provided between said opposed large faces.

3. Motor vehicle lock according to claim 1, wherein a cap that is matched to the shape of the entry slots is provided as a separate component which is fastenable on the housing for closing a one of the entry slots which is not in use.

4. Motor vehicle lock according to claim 3, wherein said cap is insertable into said one of the entry slots.

5. Motor vehicle lock according to claim 3, wherein said cap is snappable onto said housing.

6. Motor vehicle lock according to claim 3, wherein a lock hinge guideway is provided as a separate component which is mountable to said housing in association with an other of the entry slots which is in use, said lock hinge guideway being mirror symmetric with respect to a plane passing therethrough.

7. Motor vehicle lock according to claim 3, wherein lock hinge guideways are provided for each of the entry slots as separate components, one for placement on one of the large faces and the other for placement on the other of the large faces.

8. Motor vehicle lock according to claim 6, wherein the lock hinge guideway is snappable onto the housing.

9. Motor vehicle lock according to claim 6, wherein the lock hinge guideway is made of a thermoplastic plastic material.

10. Motor vehicle lock according to claim 7, wherein the housing is provided with catch receptacles for molded catches on the lock hinge guideway.

11. Motor vehicle lock according to claim 10, wherein the catch receptacles are on a narrow side of the housing.

12. Motor vehicle lock according to claim 1, wherein the large faces are separated by narrow peripheral edge faces;

and wherein a metal reinforcement plate is provided on each large face of the housing, parallel to said center plane.

13. Motor vehicle lock according to claim 1, wherein the electrical connection device is located on an outer side of said housing.

14. Motor vehicle lock according to claim 1, wherein the housing is completely closed externally except for said entry slot for the lock hinge and any entry fittings for at least one of a lock cylinder and Bowden cables.

15. Motor vehicle lock comprising an outer housing having a pair of opposed large faces, each of which is provided with an entry slot for a lock hinge having a catch, a catch pawl located in said housing which interacts directly with the catch of the lock hinge having a corresponding catch, and an electric drive located in said housing for moving said catch pawl, and an electrical connection device for electrically connecting said drive to a source of electrical power;

wherein said housing is essentially symmetrical relative to a center plane thereof that lies parallel to a plane of rotation of the catch pawl with the entry slots being elongated in essentially identical directions that are parallel to said center plane on opposite sides thereof; and

wherein said electric drive is positioned between said entry slots, the symmetry of the housing and positioning of the entry slots and electric drive enabling mounting of the housing, selectively at either of said opposed large faces for use at both left and right sides of a vehicle.

16. Motor vehicle lock according to claim 15, wherein the electrical connection device is located on an outer side of said housing.

17. Motor vehicle lock according to claim 15, wherein the housing is completely closed externally except for said entry slot for the lock hinge and any entry fittings for at least one of a lock cylinder and Bowden cables.
